There's nothing with your game or account that is preventing you from appearing on our search. When you are trying to rank for "topic" based searches, there is a lot more competition, and the search UI isn't the greatest for that. We try to push people into the browse page with a tag for topic based browsing. Search at the moment works best for direct title matches. I just added an official "Soccer" tag to make it easier to find from search.

Regarding searching by your name, search works by your username, not your display name: https://itch.io/search?q=oliver+benedens

Hope that explains what's going on.

@beggigames - whether this is useful to you or not I don't know, but I just tried a search for "hyperactive" - your game was 2nd in the list -  and "soccer" - your game was 19th.  Not surprisingly it was the first game that came up when I searched for "hyperactive soccer" specifically.  

I'll give your game a try when I can, I like the idea of these quick manic matches! :-)
